What red blooded American boy wouldn't want 4,300 HP? In my 150 HP Porsche 944 I recently dragged a 427 side oiler 1961 Ford. He was only marginally faster than I was because the Ford wouldn't put down the power. I doubt that anything other than Porta's new designs would actually work with more power than what the old engines had. And even then, everything would depend on the sanders to keep the wheels from slipping.
